ENGINE RADIATOR Filed Jan. 25, 1935 I g V mywgj/LS Patented Apr. 14, 1936 UNITED STATES PATENT OFFICE ENGINE RADIATOR Application January 25, 1935, Serial No. 3,529 In Belgium February 2, 1934 7 Claims.

The present invention relates to motors'including a cooling jacket connected with a heat radiating element. It is more especially, although not exclusively, concerned with motors of this kind in which said heat radiating element is a steam condenser.

The object of the present invention is to provide improved motors of this type which are better' adapted to meet the requirements of practice.

The essential feature of the present invention consists in so devising the heat radiating element to be provided in motors of the kind above referred to that this element can be readily displaced, either for cleaning it or for making it possible to reach organsY that are normally covered by said element.

This and other features of the present invention will ybe more specifically described in the following specification.

A preferred embodiment of the present invention will be hereinafter described, with reference to the accompanying drawing, given merely by way of example, and in which:

Fig. 1 is a vertical axial sectional view of a motor according to the present invention and consisting of a vertical single cylinder internal combustion engine;

Fig. 2 is a corresponding side view;

Fig. 3 is a horizontal sectional View on the line III-III of Fig. 2.

According to the present invention, the whole of the engine, With the exception of the cooling system thereof, is made of any conventional or other type.

As for the cooling system it includes a cooling jacket l surrounding the engine cylinder and provided with suitable inlet and outlet orifices, and a ,heat radiating element 2 adapted to cooperate with said jacket l.

According to the present invention, this heat radiating element 2 is so devised that it may be easily displaced, either for cleaning it or, for making it possible to reach organs that are normally covered by said element 2.

Accordingly, this heat radiating element is secured to the engine parts through securing means adapted to be quickly brought out of action and adapted to normally apply the inlet and outlet pipes of said heat radiating element in a iiuid-tight manner against the above mentioned inlet and outletV orifices of the cooling jacket, respectively. Advantageous-ly theinlet and outlet orifices will be juxtaposed to each other, so as to (Cl. 12S-174) permit the grouping together of the packing means to be used.

Of course, according to the present invention, the heat radiating element and the cooling jacket of the engine (or any intermediate organs carrying the orifices to be connected together) can be so arranged that these parts are Wholly independent of one another when the seeming means above referred to are in inoperative position.

But preferably, according to the arrangement shown by the drawing, these parts are always connected together, through any suitable means, and for instance, as shown by Fig. 1, through hinges 3 about which the heat radiating element 2 can pivot.

In this embodiment of the invention, the se` curing means are advantageously disposed close to the orifices of the heat radiating element to permit a secure tightening of these orifices to the inlet and outlet orifices of the cooling jacket.

The present invention is particularly interesting in the case of engines the heat radiating element of which is a condenser located above the level of the cooling liquid.

In this case, the condenser should be provided with a steam inlet oriiice 4 and an outlet tube 5 for condensed water. Advantageously, this pipe 5 is arranged to pass through the steam outlet orifice which is then provided at the top of cooling jacket I. For this purpose, said tube 5 is provided with a prolonged part 6 made of sucha length that it dips in the cooling liquid present in the jacket as long as the level of said liquid is higher than the minimum level m (Fig. 1).

It is therefore sufficient to provide a single packing device between the condenser and the cooling jacket, since each of these parts includes only one orice. For instance, as shown in the drawing, this packing device consists merely of a rubber or similar ring 1 adapted to be held between the edges of the orifices of the cooling jacket and the condenser, respectively.

With these arrangements, a very simple embodiment can be devised when it is desired to arrange, according to the invention, a vertical single-cylinder internal combustion engine the condenser of which is disposed substantially horizontally above the engine in such manner that an air stream produced by any suitable fan is caused Y' 9, the whole being surrounded by a casing I0. This casing, made for instance of metal sheets, is provided with apertures adapted to put into communication with the atmosphere the space located above the nest of tubes, while the space located underneath this nest of tubes communicates with the intake tube of the fan above mentioned.

This condenser is arranged in such manner that headers 8 and 9 are disposed horizontally above the cylinder head, on either side of the latter, the nest of tubes thus covering said cylinder head. v

The condensed water header 9 is pivoted to the cylinder head through hinges 3.

The bottom of header 8 carries the steam inlet oriice 4.

A tube 5, leading from header 9 to said orice 4, carries the prolonged part 6 above mentioned. Preferably, this tub'e 5 is so arranged that, when the condenser is in its working position, said tube is suliciently inclined for ensuring the flow of condensed water to said part 6.

At the upper part of the cooling jacket that surrounds the cylinder head, there is provided a steam outlet orifice II of a size corresponding to that of orice 4 and disposed opposite said orifice 4. Advantageously, packing member 'I is supported about said orice II.

Between header 8 and the cylinder head, there are provided securing means adapted to be quickly brought out of action, said means consisting for instance of a stirrup I2 pivoted to header 8 and carrying a securing screw I3 having a milled head, adapted to bear against a projecting part I4 of. the jacket.

Although casing I0 may be made .rigid with condenser 2 so that both parts can pivot together, for instance through an angle of about hinges 3, it is believed more advantageous to provide, for each of these parts, a separate articulation, whereby it is possible, if so desired, to lift casing IU without displacing condenser 2.

For this purpose, said casing may be, for instance pivoted, independently of the condenser, about hinges coaxial to hinges 3.

It is also obvious that casing II] might be carried in a removable manner by the condenser without being connected thereto through hinges.

This casing may, for instance, surround the condenser at the upper part and also on the sides and it may also be joined with other casing elements I5 disposed on the front and on the rear of the condenser. But in any case casing Ill is so arranged as to compel air to iiow through the nest of tubes.

It will be readily understood that, owing to the arrangements that have been above described, when the condenser is swung into the open position it is possible to reach the organs located under it on the cylinder head, such for instance as Injector I6, if. the latter is so positioned.

This will make it possible to devise the upper part of the engine without being limited by the fact that some organs cannot occupy certain positions in which they could not be reached, due to the presence of the condenser, when said condenser is permanently fixed to the engine. For instance, the injector I6 can be placed at the center of the cylinder head, immediately under the nest of'tubes of the condenser, pipe 5 being, of course, in this case, bent so as to leave room for said injector.

With this arrangement, it will be advantageous to provide the condenser (and for instance the nest of tubes of said condenser) with a kind of bell I'I so arranged that, when the condenser is in working position, said bell covers the injector and its edges t against the portion of the surface of the jacket that surrounds the injector.

Said injector is then enclosed in a chamber into which dust contained in the air that flows through the condenser cannot enter.

Of. course, this bell moves together with the condenser and does not in any way prevent access to the injector when the condenser is swung up in the open position. As for tube 5, it is advantageously disposed on the outside of said bell.

'I'he operation and the advantages of the system above described are believed to result clearly from the preceding description.

It should be noted that the organs located under the heat radiating element are not necessarily an injector, as diagrammatically shown at I6, but might consist of valves, with their springs, their control organs, etc.

In a general manner, while I have, in the above description, endeavoured to disclose what I deem to be practical and eflicient embodiments of the present invention, it should be Well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition and form of theparts without departing from the principle ofw the present invention as comprehended within the scope of the appended claims.
